British History Online is a collection of nearly 1300 volumes of primary and secondary content relating to British and Irish history, and histories of empire and the British world. BHO also provides access to 40,000 images and 10,000 tiles of historic maps of the British Isles.
Because of the UK lockdown, we made all of our transcribed content free until 31 July 2021. This was to support the work of researchers, teachers and students when library and archive access was difficult or impossible. We have now returned to our subscription model, where some of our material is paywalled. At this moment (late February 2024) subscribing has been disabled, pending an imminent server and software upgrade. The majority of content is, however, still free to access.
